Room lamp

Abstract

The invention relates to a room lamp (1) which is designed to light a space under different angles and in a controlled manner, and which comprises—a plurality of different light emitting elements (122); and—a first illumination body (100) with a plurality of light directing devices at each of which a light emitting element (122) is arranged, each light emitting element emitting light in a light-guiding direction. At least one light directing device (102, 104, 106, 108, 110, 112, 114) has a collimation portion (124), in which the light rays of the light emitting element (122) that is arranged in the light directing device are parallelized, and a plurality of prism portions, each of which deflects a part of the parallelized light rays (126, 128, 130). The invention also relates to a method comprising the following steps:—controlling, by way of a gesture on a touch-sensitive display screen of a portable electronic device, the size and/or color and/or brightness of at least one area to be lighted;—detecting the orientation of the portable electronic device and of the room lamp; and—transmitting to the room lamp the size and/or color and/or brightness of the area to be lighted depending on the orientation of the portable electronic device and/or of the room lamp.
